From f4428a5b6f63ed6df86da17eb19c2e629ae1b1f3 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 19 Nov 2025 01:25:20 +0000 Subject: [PATCH 1/3] Add comprehensive GPU performance prediction models This commit implements three approaches for cross-GPU performance prediction: 1. Analytical Model (roofline + occupancy) - Physics-based approach using roofline model and occupancy theory - Updated to include Titan X GPU data - Generates predictions for 3 experiments (new GPU, new config, new kernels) 2. ML Baseline (Random Forest) - Machine learning baseline with ~35 features - Kernel characteristics + GPU specifications - Updated to include Titan X GPU data 3. Hybrid Enhanced Model (BEST - Main Contribution) - Physics-informed ML combining analytical + data-driven approaches - 60+ enhanced features including: * Analytical model outputs (occupancy, roofline, efficiency) * Ratio features (compute_ratio, bandwidth_ratio, etc.) * Cache awareness (working_set_per_l2, cache_residency) * Memory pattern encoding (one-hot for coalesced/strided/random/atomics) - XGBoost or Random Forest with log-transform - Feature importance analysis for interpretability Key Files: - data/gpu_metrics.json: Unified GPU specifications for all 4 GPUs - scripts/analytical_model_occupancy.py: Updated analytical model -

Now all intermediate problem sizes are used for training, providing much better data for learning scaling behavior. Changes: - Modified compute_config_roles() in all 3 model scripts - For kernels with 3+ configs: baseline, train_extra (ALL middle), test_extra - 15 kernels with 5 configs each now provide 3 training configs instead of 1 - Exp2 training data increased by 2x for most kernels This should significantly improve ML model performance on Exp2 (scaling prediction). ---
